le it known that I, HERBERT `H. STEELE,

' citilzen ot' the United States, and resident of lllarccllus, in thecounty of Onondaga and State of New York, have invented certain new anduseful Improvements in Type- VWriting Machines, of which the following-a specification.

' VMy invention relates to platens and paper feeding mechanism fortypevvriting Inaehincs and its object generally is to provide improvedmeans for controlling the part-s of' a divided or sectionalv platenandthe work sheet or sheetsfed thereover. l.

While the principles of myvinventlon are .applicable generallysaidinvention relates' specifically to improvements on the inven tions shownin my 'Patents Nos. 1,052,021`

' and 1,052,186, both granted February 1,

4 so doing it is possible to turn the platen ,gether and. at the lncarrying out my presentinvention I provide, as before, for'automatically unlocking that. one of the ,platen sections which isnormally locked against rotation and for .concurrentlyv coupling orconnecting the two platen sections s o that they may be turned or spacedequally together, but in the.

vpresent instance I also provide/in addition for yvarying the connectionbetween the two platen sections as for example by shiftable gearmechanism soas to `vary the relative extents of simultaneous movementand the relative ratesot speed of said sections. By

tion on which the record sheet is fed to a less extent and ata slowerrate than the vother section so as to obtain a greater condensation ofthe record entries.

means are provided by the present invention for rendering inoperative atwill the platen Further,

lock ot' the prior constructionand for concurrently coupling'thesections together so that at a line spacing operation they may in allpositions of the carriage be turned toL saine rate of speed, thusprovidiingr for their unrestricted usc'as a single unitary platen. l n

lo the above and other ends my invention consists in the 'Features ofconstruction, coinbinations of devices and arrangements ofy partshcreiim'fter described and particularly pointed out in the claims.

The member 58 is' held from leftward in thema-nnerpresently to be described, its movement will be resisted by the spring.

will swing said lower end backward until movement` lengthwise of theshaft 62 by the collar 77 which coperates with the left-handv y endofthe hub 61,while a second collar 78 ment thereof along theshaft 62.The collixed to theshaft ftothe right ofv the member 58will preventrightward move` lars 77 land v78, vhowever,- permit-the frame 58 to turnor move freely to limited extents on its support62 under the actionl ofthe ed ona stationary part of the machine in tion 'and couple it withthe left-hand platen only on'the left-hand platen section f whichv willturnindepen'dently ofthe rightfhand platen sect-ion',the'l'atterfremaining quies-v orderto unlock the right-h`and platen secjsection. It is obvious that when the locking toot h69 is in operationand the platen sections-are disconnected sa' line spacing oper- 8'0"ation of the finger piece-17 willbe effective cent dl'iring linespacing operations of the` 8'5- .left-hand platen section so long astheilock 69 is effective and the' two platen sections vare disconnected.`This-will be the case, under '1 the conditions heretofore described,,so long .v las the left-hand platen section is within the ield of thetypes and the right-handplaten section is outside. the printing field.lIn the present instance theactuating'device afore- "said for effectingthe unlocking of the righthad section and the coupling thereof to'the'left-hand section `is in 'fthe' form of. al camA bar'79 which isarranged to intersect'the angular in cross section and -is suitablysecuredasby' screws 80 at its left-hand 'end portion to thetop plate Q.Said bar,v howpath of the edge '74 ofthe locking member I 'I 58. Saidcam bar as shown in Fig. 5'is` l ever,'eXtends rightward beyond the topplate audits overhanging portion may be secured rigidly field of .theAtypes the 'edge 74 will engage with the stationary curved device or cam84: with the result that as the leftward `movement of the platencontinues the edge 74 will be forced forward, swingir'1g` .the member 58on itsaxis. This swinging movement disengages the .tooth 69,'unlockingthe right-j hand platen or section which it previously had beenprevented from turning during the operations of the line spa'ce handleor lever the pinion 52 into meshwith the gear wheel and assuming thatthe parts are arranged as in Fig. 4 Will-swing the pinion 56 into 'meshwith the gear, wh'eel 44. `The pinion Also such swinging movementcarries scribed the platen or section 24 will bere-A leased from thelocking or detent devices which normally prevent it .from being turnedand Will be connected through the gear wheels 35 and 44 and theircoperating pinions with the left-hand platen section. The artsare'arranged so that the pinion 52 will partly engage with the gear 35before said gear is entirely freed from the control of the locking tooth69. The position of vthe parts following the described opera- 'tion isillustrated in Fig. 2. The actuating device 79, 84 is'yarranged toeffect the results described as the right-hand laten section enters theprinting field, an it will be understood that during further leftwardmovement of the two-part platen said .device or cam fbar will voperateto maintain the pinion's"engaged` with their gears as illustrated inFig. 2 so that a turning or line fed over the right-hand section of theplaten,l

spacing movement communicatedto the'lefthand platen -section from theregular line spacing devices will be participated in by the right-handplaten section. Owing, howeve-r, to the differential gear connectionsbetween the two platen sections the right-hand platen section will turnat a slower rate and to a less extent than -Will the left-hand section.In the present instance the parts are so proportioned and related thatif a line 'spacekmovement of tWo units be communicated to the left-handplaten section by operation of the linger piece 17 the correl -spondingvmovement of the right-hand sect`ion`Will amount to a little more than asingle Aunit of line space movement. This feature of my presentinvention enables it to be employed to advantage in various-v kinds ofcommercial typevvriting such as railroad Waybilhng, or accounting, orthe like, wherein a series of Waybills or'invoices. are to be Wrlttenand a record 1s to be kept l of certain data from each bill. In suchcases the Waybills or bill sheets or invoices may I, be fed overl theleft-hand. platen section while the recordv for each bill which in'cludes all -data that may be essential may be Written in a single lineon a record'sheet said record sheet being if desired a continuousA stripor web. By employing my present invention in the mannerdescribed thelines on the `right-hand or record sheet arespaced a little more than asingle'line space distance apart, although the line spacing de-`vicesincluding the paWl 14 A4and the finger piece 17 are set for doubleline'spacing and such double line spacing or .two units of line-spacemovement will be communicated to the left-hand platen section at timeswhen the rightfhand platen section is receiving slightly in. excess of asingle imita line space less than two units for the reason that thebills are usually press copied and it is not feasible to make a goodpress copy when the spacing is closer than double line spacing. On`theother hand, it is preferable not to reduce the line spacing on therecord sheet quite to a single unit for the reason that in .commercialtypewriters where billing numerals are employed certain characters wouldwith the usual single line spacing overlap at their tops and bottoms.

If the nature of Work is such, as is the case in some systemsofcommercial book-keeping, that it is desirable to feed or rotate theright-hand platen section unjformlyfvvith the left, it is only necessaryas a preliminary to change or shift the pair of gears or two-part gearWheel 38, llir to the right in the manner explained and to reset saidtwo-part Wheel or pair of gears by causing the pin 49 to engage With`the hole 51. When thus reset the gear Wheel 38 will be oppositeto or inregister with the pinion 55 While the gear Wheel 44 will be out ofregister With or in a different fore and aft plane from the pinion 56.'Consequently When the frame 58 is swung forward to couple the platensections, movement will be communicated from the left-hand platensection to the right-hand platen section through a gear train comprisingthe 55 and 52, and the gear Wheel 35. As a result, the two platensections will be spaced or advanced simultaneously andto uniformextentsun'der a single actuation of the fin 'ge/r p1ece17 when theright-hand platen section-isdn the printing field.

"7W/Vith the locking devices COIIIPI'Sing the locking tooth 69 inoperation it is not possible to rotate the right-hand platen sec; tionwith the left-hand platen section under the adjustment of the parts lastdescribed except at times when the right-hand platen section is oppositethe printing point, since at all other times the locking tooth 69 is 'inengagement with the gear wheel 35 andl locking tooth 69 is held out ofaction and the connecting devices comprising the pinions 55 and 52 aremaintained 1n mesh with their cooperating gear wheelsj38 and 35.'
